Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@bindiff-mcp Compare ./httpd-2.4.57 and ./httpd-2.4.58; list changed functions"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
MCP server that gives reverse-engineering agents binary diffing: export binaries to BinExport v2 and compare two builds with BinDiff.
IDA is driven through ida-nexus, so a binary already open in the IDA GUI is exported from that database (renames and annotations included); otherwise a headless idalib worker is spawned and released again when the export finishes. Export and diff parsing reuse python-binexport and python-bindiff.
IDA Pro 9.x with idalib enabled (idapyswitch), IDADIR pointing at the install
The BinExport IDA plugin (binexport12_ida.so) in $IDAUSR/plugins
The BinDiff differ (bindiff) in PATH, in $BINDIFF_PATH, default at
/opt/zynamics/BinDiff/bin

uv pip install .bindiff-mcp stdio # stdio transport (default)
bindiff-mcp http --host 127.0.0.1 --port 8745 # Streamable HTTP at /mcpRegister with Claude Code:
claude mcp add bindiff -- bindiff-mcp stdio
claude mcp add bindiff --transport http http://127.0.0.1:8745/mcpbinexport(binary, output_results_dir=".")Exports binary to <output_results_dir>/<binary name>.BinExport. An export
that is at least as new as the binary is reused instead of re-analyzing it.
Returns JSON:
{
"binary": "/work/httpd",
"binexport": "/work/out/httpd.BinExport",
"reused": false,
"name": "httpd",
"architecture": "x86-64",
"sha256": "...",
"functions": 2317
}bindiff_compare(primary_binary, secondary_binary, output_results_dir=".")Exports both binaries in parallel (into primary/ and secondary/
subdirectories, so identical file names cannot collide), runs the differ, and
writes four JSON files into output_results_dir:
File | Content |
| matched functions with similarity 1.0 (identical) |
| matched functions that changed, most divergent first |
| functions only in the primary binary |
| functions only in the secondary binary |
Match entries carry both addresses and names, the similarity and confidence
scores and the BinDiff algorithm that produced the match; unmatched entries
carry address, name and function type. The tool returns JSON with the overall
similarity and confidence, the .BinDiff database path, per-list counts and the
path of every file written.
